NUMERAL IMPRINTING DEVICE This invention relates to a check writer for imprinting a necessary sum of money on a sheet of paper such as a check, receipt and bill, etc.

Heretofore, it has been the practice to imprint a necessary sum of money in an enlarged scale on the main print portion of a check, receipt, bill, etc. whilst the same sum of money is hand written in a reduced scale on the copy portion thereof with the result that such hand writing takes time and is troublesome and eventually there is risk of the sum of money being erroneously written.

The principal object of the invention is to provide a check writer which is capable of imprinting a necessary sum of money in an enlarged scale on the main print portion of a sheet of paper such as a check, receipt, bill, etc. whilst at the same time of imprinting the same sum of money in a reduced scale on the copy portion thereof in a simple and reliable manner.

Another object of the invention is to provide an improved type check writer having a device for operating ink pads with which imprinting on the main print and copy portions of the sheet of paper can clearly be effected.

For a better understanding of the invention, reference is taken to the accompanying drawings, in which:

FIG. 6 is a sectional view showing the mechanism for selectively operating the lower paper feed rollers in details;

FIG. 7 is an end view illustrating the sheet of paper driven by the main type wheel relative to the copy type wheel;

FIG. 8 is a plan view showing a receipt imprinted with the same numerals and symbols representing the sum of money in an enlarged scale on the main print portion and in a reduced scale on the copy portion;

FIG. 9 shows similarly to-FIG. 2 a plan view of a check writer provided with ink pads and a device for operating the ink pads; and

FIG. 10 is a front elevation of the device for operating the ink pads shown in FIG. 9.

Referring to the drawings, reference numeral 1 designates a stand provided at its each side with a side wall 2 secured thereto and projected therefrom and each side wall 2 being interconnected with the other through a base plate 2'.

Across the side walls 2, 2 is arranged a pivot shaft 3 which pivotally supports a frame 4. The frame 4 is provided at its rear end with a spring 5 which serves to normally incline the front end of the frame 4 upwards by a certain angle with respect to the stand 1. A shaft 6 extending through and in parallel with the frame 4 is rotatably journalled therein and provided outside the frame 4 with a main type wheel 7 with a conventional positioning wheel 8, a conical shaped dial 9 with numerals and symbols arranged circumferentially thereabout, and a handle 10 formed integral therewith.

The shaft 6 is provided at its rear end with a rotary bar 11 secured thereto and having a pin 12 projected from one end thereof and adapted to be brought into engagement with a U-shaped arm 13 secured to a pawl 14 which is pivotally supported by the rear end of the frame 4 and normally in engagement with a ratchet wheel 15 by means of a spring 16 as clearly shown in FIG. 6.

The ratchet wheel 15 is secured to the rear end of a lower shaft 17 rotatably journalled in the stand 1 as shown in FIGS. 1 and 5 and rotatably supports a pair of lower paper feed rollers 18, 18 arranged beneath the stand 1. Beneath the stand 1 is arranged another lower shaft 19 extending in parallel with the shaft 17 and rotatably supports another pair of lower paper feed rollers 20, 20.

Adjacent to the other side wall 2 is pivotally supported by the pivot shaft 3 another frame 21. The frame 21 is provided at its rear end with a spring 22 which serves to normally incline the front end of the frame 21 upwards by an angle substantially equal to the angle made by the frame 4. A shaft 23 extending through and in parallel with the frame 21 is rotatably journalled therein and provided outside the frame 21 with a copy type wheel 24.

The frame 4 is provided at its one side with a bracket 25 extending inwards and provided at its free end with an adjusting screw 26 which engages with the top surface of the frame 21 to cause the main type wheel 7 and the copy type wheel 24 to be moved together. The adjusting screw 26 serves to hold the main type wheel 7 and the copy type wheel 24 in a predetermined positional relationship relative to one another.

In the embodiment shown in the drawings, the copy type wheel 24 is made smaller in diameter than the main type wheel 7. Around the periphery of the main and copy type wheels 7, 24 are arranged types representing a series of numerals, symbols, etc. to be printed on a sheet of paper 27 (FIG. 7) such as a check, receipt, bill, etc., such that the same numeral or symbol is located on each of the corresponding radii of these two wheels 7, 24. The copy type wheel 24 is adjustably mounted on the shaft 23 such that its lowest type is made in alignment with the lowest type of the main type wheel 7 and also in opposition with a print line on the sheet of paper 27. For this purpose, the shaft 23 may be adjustably moved in its lengthwise direction. To the shafts 6 and 23 are secured sprocket wheels 28 and 29, respectively, which are substantially the same in diameter and driven in synchronism by means of a chain 30 when the sprocket wheel 28 is rotated by the handle 10 so as to bring the same numeral or symbol selected from the series of numerals or symbols arranged circumferentially about the main and copy type wheels 7, 24 into the positions in opposition with the print line on the sheet of paper 27.

The types representing a series of numerals, symbols, etc. may be formed around the peripheries of the main and copy type wheels 7 and 24 by the conventional way of securing types made of soft metal to the outer peripheries thereof or of making these types integral with the latter.

Under the main and copy type wheels 7 and 24 are arranged two pairs of upper paper feed rollers 31, 31

and 32, 32 for feeding the sheet of paper 27. These rollers 31, 31 and 32, 32 are arranged at corners of a cross plate 33 secured to the front end of a leaf spring 34 whose rear end is secured to the pivot shaft 3. The cross plate 33 is provided at its each side with notches 35, 35 through which extend the main and copy type wheels 7, 24 and abut through the sheet of paper 27 against type seats 36, 37 secured to the top surface of the stand 1, respectively, as shown in FIG. 3.

The leaf spring 34 is provided at its free end with a cam 38 with its top surface inclined. Provision is made of an L-shaped bracket 39 whose long leg extends in parallel with the leaf spring 34. The bracket 39 is secured at the end of its short leg to the base plate 2' of the stand 1 and provided at the free end of the other long leg extending also in parallel with the stand 1 with a two armed lever 40 which is pivotally supported by the bracket 39. The downwards extending arm 40 of the two armed lever 40 is normally urged by the spring action of the leaf spring 34 against the bottom portion of the inclined surface of the cam 38 to maintain the cross plate 33 and hence the pairs of the upper paper feed rollers 31, 31 and 32, 32 in raised positions thereof. If the upwards extending arm of the two armed lever 40 is pushed downwards against the spring action of the leaf spring 34 to bring the downwards extending arm 40 into engagement with the top horizontal portion of the inclined surface of the cam 38, the leaf spring 34 and the cross plate 33 and hence the pairs of the upper paper feed rollers 31, 31 and 32, 32 are pressed downwards. Between the cross plate 33 and the stand 1 is arranged a sheet restraining plate 41 whose rear end is secured to the base plate 2'. The sheet restraining plate 41 is provided with openings 42, 42 through which extend the pairs of upper paper feed rollers 31, 31 and 32, 32 and the main and copy type wheels 7 and 24. The sheet restraining plate 41 is spaced apart from thetop surface of the stand 1 to form a gap through which is inserted the sheet of paper 27 such as the check, receipt and bill.

The above mentioned pairs of lower paper feed 18, 18 and 20, 20 are located in opposition with the pairs of upper paper feed rollers 32, 32 and 31, 31, respectively, as shown in FIG. 4. The lower paper feed rollers 18, 18 and 20, 20 are secured to the shafts 17 and 19, respectively, such that the upper surface of each lower paper feed roller extends through and is projected out of the top surface of the stand 1, the shafts 17 and 19 being rotatably journalled in fittings 43 and 44 secured to the bottom surface of the stand 1, respectively. The shaft 17 for supporting the lower paper feed rollers 18, 18 and located below the main type wheel 7 is provided at its rear end with the ratchet wheel adapted to be normally engaged with the pawl 14 pivotally supported by the rear end of the frame 4 and urged against the ratchet wheel 15 by the action of the spring 16 as shown in FIG. 6.

To the shaft 17 is secured a sprocket wheel 45 which is connected through a chain 46 to a sprocket wheel 47 secured to the rear end of the shaft 19 and having a diameter which is larger than that of the sprocket wheel 45.

When the handle 10 is pressed downwards against the action of the spring 5 so as to move upwards the rear end of the frame 4 around the pivot shaft 3, the pawl 14 pivotally supported by the rear end of the frame 4 moves upwards sliding along the ratchet wheel 15. On the contrary, if the handle 10 is released and is moved upwards by the action of the spring 5 to move downwards the rear end of the frame 4 around the pivot shaft 3, the'pawl 14 is brought into engagement with the ratchet wheel 15 by the action of the spring 16 to rotate the ratchet wheel 15 with the result that the shaft 17 and hence the lower paper feed rollers 18, 18 are rotated.

Therotation of the shaft 17 causes the shaft 19 and hence the lower paper feed rollers 20, 20 to rotate at a rate slower than that of the shaft 17 and the lower paper feed rollers 18, 18. Thus, the sheet of paper 27 such as the check, receipt and bill inserted between the upper and lower paper feed rollers are driven at a higher rate at the side of the main type wheel 7 and driven at a lower rate at the side of the copy type wheel 24 thereby forcedly sagging the sheet of paper 27 into a cavity 48 formed at the center of the front end of the stand 1 as shown by dot-dash lines in FIG. 7. The longitudinal length of the cavity 48 is made larger than the width of the sheet of paper 27 In FIG. 8 is shown a receipt as an example of the sheet of paper 27 in which the sum of money is imprinted in an enlarged scale on a main print portion A while the same sum of money is imprinted in a reduced scale on a copy portion B.

The gear ratio between the sprocket wheels 45 and 47, i.e., the relative rate of feeding the main print and copy portions A and B of the sheet of paper 27 is determined by the relative spacing between successive numerals or symbols to be printed on the main print and copy portions A and B of the sheet of paper 27.

If it is desired to imprint the sum of money on the sheet of paper 27 such as the check or receipt, the sheet of paper 27 selected from a check book or receipt book is slipped into the space between the sheet restraining plate 41 and the stand 1 with the main print portion A located below the main type wheel 7 and with the copy portion B located below the copy type wheel 24. Then, the two armed lever 40 is pushed downwards so as to move downwards the upper paper feed rollers 31, 31 and 32, 32, thereby resiliently holding the sheet of paper 27 between these rollers and the lower paper feed rollers 20, 20 and 18, 18. Then, the handle 10 is rotated to select a desired numeral or symbol from the series of numerals and symbols arranged circumferentially about the main type wheel 7 and locate it directly below this wheel 7 and in opposition with the main portion A of the sheet of paper 27 If the handle 10 is rotated, the copy type wheel 24 is simultaneously rotated through a transmission mechanism consisting of the shaft 6, sprocket wheels 28, 29 and chain 30 to select and locate the same numeral or symbol directly below this wheel 24 and in opposition with the copy portion B of the sheet of wheel 27. Then, the handle 10 is pressed downwards against the action of the springs 5, 22 to imprint the same numeral or symbol located in opposition with the sheet of paper 2'! simultaneously on both the main print and copy portions A and B. Then, the handle 10 is released to bring back the main and copy type wheels 7 and 24 into their normal positions shown in FIG. 1 by means of the springs 5 and 22, respectively. During this return movement of the handle 10, the pawl 14 secured to the rear end of the frame 4 is brought into engagement with the ratchet wheel 15 to rotate it, with the result that the lower paper feed rollers 18, 18 and 20, 20 are driven to feed the sheet of paper 27. In the same manner, the handle is successively rotated and then pressed downwards to imprint the same numerals and symbols such as 987,654,000 on the main print and copy portions A and B of the receipt 27 as shown in FIG. 8.

The rate of feeding the copy portion B of the sheet of paper 27 driven by the lower paper feed rollers 20, 20 is made slower than the rate of feeding the main portion A driven by the lower paper feed rollers 18, 18 so that the sheet of paper 27 is sagged down in the cavity 48 formed in the stand 1 with the result that the series of the numerals and symbols arranged circumferentially about the copy type wheel 24 can be imprinted on the copy portion B with a required reduced type spacing at the same time when the series of the numerals and symbols arranged circumferentially about the main type wheel 7 are imprinted on the main portion A with the enlarged type spacing. Thus, the numerals and symbols arranged circumferentially about the copy type wheel 24 can reliably and clearly be imprinted on the copy portion B in a rapid and smooth manner.

If it is desired to imprint symbols such as comma which does not need feeding of the sheet of paper 27, the handle 10 is rotated to select and locate the comma at the lowest position of the main type wheel 7 and in opposition with the sheet of paper 27 Then, the pin 12 projected from the rotary bar 11 secured to the rear end of the shaft 6 is brought into engagement with a projection 49 of the U-shaped arm 13 made integral with the pawl 14 to disengage the pawl 14 from the ratchet wheel 15 against the action of the spring 16. Thus, the downward movement of the rear end of the frame 4 causes no feed of the sheet of paper 27, thereby simultaneously imprinting the comma on both the main and copy portions A and B of the sheet of paper 27 without interposing any space after the preceding printed numeral.

Referring to the embodiment shown in FIGS. 1 through 8 of the drawings, the novel check writer of the present invention is shown in a form for use in a sheet of paper 27 such as a receipt book or check book, etc. whose copy portion B arranged substantially in alignment with the main print portion A. The invention is applicable to other types of sheets of paper. If the sheet of paper 27 is provided with more than two copy portions B, provision may be made of a plurality of copy type wheels 24 corresponding in number to the copy portions B and interlocked with the main type wheel 7 such that the same numeral or symbol can simultaneously be imprinted on one main print portion A and more than two copy portions B. If the sheet of paper 27 is provided with the copy portion B displaced upwards or downwards from the position which is in alignment with the main print portion A the copy type wheel 24 may be slidably adjusted along the shaft 23 and secured to that portion of the shaft 23 which corresponds to the displaced copy portion B. If the size of the main print portion A is the same as that of the copy portion B, the main and copy type wheels 7 and 24 may be of the same diameter and the same gear ratio may be adopted for the paper feed sprocket wheels 45 and 47.

In FIGS. 9 and 10 is shown a device for operating pads. As shown in FIGS. 9 and 10 the main type wheel 7 is provided along its outer peripheral surface with an arcuate arm 50 having pads 51, 51 rotatably supported by each end thereof. The arcuate arm 50 is secured at its center to the free end of a leaf spring 52 secured to the frame 4. The leaf spring 52 normally urges the pads 51, 51 against the outer peripheral surface of the main type wheel 7. The shaft 6 for the main type wheel 7 and the shaft 23 for the copy type wheel 24 are provided with rotary plates 53, 54 loosely coupled adjacent the outer and inner end faces of the type wheels 7, 24 with the shafts 6, 23, respectively. These rotary plates 53, 54 are connected each other by a link 55. Each rotary plate is of substantially L-shape having upper and lower legs. The rotary plate 53 is provided at its lower leg with a supporting piece 56 having one end pivotally mounted thereon. The supporting piece 56 is provided at its free end with a pad 57 which is normally urged against the main type wheel 7. The rotary plate 53 is eccentrically provided at its lower right side with a pin 58 which is secured at its one end to the rotary plate 53. The other end of the pin 58 engages with an elongated hole 53 formed at the end of a bracket 60 secured to the side wall 2 and having an inwards bent portion extending towards the rotary plate 53.

The rotary plate 54 is provided at its upwards extending arm with a stopper 6] for limiting the rotation of the frame 21 and provided at its downwards extending arm with a pad 62.

Between the supporting shaft of the pad 62 and the shaft 23 is arranged a spring 63 which normally urges the pad 62 against the type surface of the copy type wheel 24.

If the handle 10 is pressed downwards, the frame 4, 21 and hence the main and copy type wheels 7, 24 and the supporting shafts 6, 23 thereof are pressed downwards. Since the rotary plates 53, 54 are loosely coupled with the supporting shafts 6, 23 respectively, and the pin 58 is projected from the rotary plate 53 and engages with the elongated hole 59 formed in the stationary bracket 60, if the supporting shaft 6 is moved downwards, the rotary plate 53 is rotated about the pin 58 in a counter clockwise direction as shown by an arrow and at the same time the rotary plate 54 is also rotated about the shaft 23 in a counter clockwise direction through the link 55, thereby escaping the pads 56, 62

out of the paths which are to be followed by the type I surface of the main and copy type wheels 7, 24.

After the print, if the handle 10 is released, the main and copy type wheels 7, 24 and their supporting shafts 6, 23 are moved upwards by the action of the springs 5, 22. Thus, the rotary plates 53, 54 are moved in clockwise direction to bring back the pads 57, 62 into their original positions located at directly underneath the lowest circumferential position of the main and copy type wheels 7, 24, respectively, as shown in FIG. 10. The above mentioned reciprocal up and down movement of the pads 57, 62 is repeated at each print of the respective numeral or sumbol arranged circumferentially about the main and copy type wheels 7, 24, thereby reliably inking that type of the series of types which is to be imprinted on the sheet of paper 27.

As explained hereinbefore the use of the measures described ensures simultaneous imprinting of the sum of money on both main print portion and copy portion of a sheet of paper such as a check book, receipt book, bill book, etc., and further provides the important advantage that the time requires for hand writing the same sum of money on the copy portion as has been encountered in the conventional check writer can be considerably shortened, and that a check, receipt, bill, etc. imprinted with a necessary sum of money on both main print and copy portions can be prepared in a rapid manner without error.

As stated hereinbefore, according to the present invention, the rotary plates 53, S4 loosely coupled with the shafts 6, 23, respectively, and interlocked each other by the link 55 are utilized as means for reciprocally moving the pads 57, 62 into engagement with and disengagement from those types of the series of numerals and symbols arranged circumferentially about the main and copy type wheels 7, 24 which are located in opposition with the print line on the sheet of paper. This renders it possible to attain an effective inking for the types to be printed at every printing time in dependence with the simple pressing down and release opera tion of the handle 10. Thus, with the device for operating the ink pads of the invention, the print can always be effected in a clear and smooth manner. Moreover, the check writer according to the invention is simple in construction and reliable in ope-ration. Therefore, the invention contributes greatly to the industry.
